This report a study of the potential use of corn oil as an alternative to mineral oil by improving its insulation performance under AC voltage by adding SiC fillers. The experiment was performed to get the breakdown voltage (V_{bd}) value of the Corn Oil with SiC addition at concentrations of 0; 0.25; 0.5; 0.75; and 1 wt%. In this experiment, Shell Diala B is used as a comparison to mineral ins…
